Pearson and Denham was a retailer of photographic goods in Leeds, UK, until some time in the 1960s.[1] The company premises were in Bond Street, in central Leeds. The company was started in the 19th century; they only made cameras for a short time.[2][3]

Cameras

The Loidis, about 1890: a double-extension half-plate (4¾×6½ inch) field camera, with rear focusing.[2] Loidis, or sometimes Leodis, is the name of the Romano-Celtic settlement where Leeds now is.

↑ 3.03.1 A picture of the back of the Standard is shown in this forum post on photo.net (the same enquiry was made on Large Format Photography). The camera is said to have a Dallmeyer Rapid Rectilinear lens. One respondent on photo.net suggests the company moved away from making cameras gradually, so some may have been made between 1910 and 1920.
